Select Edit Web Part from the PeopleZen Web Part menu and in the settings
tool-pane, scroll down to the Paging section:

At its top, this section lets you specify the maximum number of user profiles to
show per "page". The default value is 6 and this simply means that no more
than 6 user accounts will ever be listed at once in the Web Part. If there are more
profiles then "paging links" will be shown at the top, allowing end users to navigate
forward or backward in the people listing. To disable paging, simply enter
0.

You can also customize how these paging links are displayed:

Show current position: — lets you set how to indicate which sub-set
of the overall listing is currently shown:

(Person) x - y of z — on a listing of 10 people with 4 per page, the
second page would show: 5 - 8 of 10

(Page) x of y — on a listing of 10 people with 4 per page, the second
page would show: 2 of 3

First/Last links: — lets you customize whether and how users can skip
pages to navigate directly to the very beginning or the end of the entire listing:

Text Links — textual links are used, with the labels First and
Last (customizable via the DIY User Interface Localization tool in
PeopleZen Studio)

Arrow Icons — small graphical icons are provided for going to the beginning
(left arrow) or the end (right arrow)

(None) — no paging links for skip-based navigation are provided
